RE: gun rusting
Do noy spray any oil or lubricant where it can run down into the bedding.I have seen groups double or triple after oil flowed between the bedding and the action.Once the action and stock were cleaned to remove the oil the accuracy returned to normal.Also do not spray oil into the trigger mechanism as it can gum things up and cause problems.Spray the oil on a rag and use it to wipe down the metal surfaces.
